HCl varied with substitution at C-11, while no addition of HF was observed at all. The 7 alpha-fluoro corticosteroids were prepared by reaction of the appropriate 7 beta-hydroxy compounds with N,N-diethyl(2-chloro-1,1,2-trifluoroethyl)amine. The 7 beta-hydroxy steroids were obtained, in turn, from the 6,7-dehydro compounds via the 6 beta,7 beta-dihydroxy derivatives. Antiinflammatory potencies were measured
